Will air leak in through the mechanical seal when the pump is not in operation?
Thread Content
Since there is no leakage from the mechanical seal either when the centrifugal pump is shut down or while it is in operation, is it possible for air to get into the seal during shutdown? Or is it possible for air to get in at the moment of startup? How to tell?
Seals are subject to limitations imposed by pressure differences in their operating conditions; not all seals can function under all pressure conditions. Additionally, some seals also exhibit directionality under special pressure conditions. It would be best to share the actual problems that arise on site so that targeted discussions can take place for reference.
